PHILIP SCHWICKART, OF NEW YORK, N. Y.

BUILDING LIGHT AND VENTILATOR.

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application filed February 6, 1911. Serial No. 606,749.

To all whom it may concern:

Be it known that I, PHILIP ScrrwroxAR'r, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Im-' proved Building Light and Ventilator, of which the following is a full, clear, and eX- act description.

The invention. relates to sky-lights, wall lights and similar building lights, and its object is to provide a new and improved building light and ventilator, arranged to insure a proper illumination of the space below by the use of reflected rays of light, and to provide a thorough ventilation of the said space.

For the purpose mentioned, a reflector, open at the top, is mounted below a casing provided with lenses, so that some of the rays of light refracted by the said lenses and falling onto the outer surface of the reflector are reflected by the latter laterally, while other rays of light refracted by the said lenses pass through the top opening of the reflector into the space below the same.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a sectional side elevation of the illuminating device; and Fig. 2 is a sectional plan view of the same on the line 2-2 of Fig. 1.

The roof or ceiling A of a room or other space B to be illuminated and ventilated, is provided with a rectangular or other open ing C, in which is fitted a casing D, having a top in the form of a building light E, that is, a frame and lenses set in cement therein, the said building light being preferably of the construction shown and described in the Letters Patent of the United States, Nos. 889,724 and 894,708, granted to me on June 2, 1908, and July 28, 1908, respectively, and No. 922,964, for a lens for building lights, granted to me on May 25, 1909.

A reflector F is suspended by rods G from the casing D, and the said reflector F is arranged centrally relative to the casing D. with the upper end of the reflector F approximately flush with the under side of the roof or ceiling A. The reflector F is provided with sides extending upwardly and inwardly from the base of the reflector F to the top thereof, which latter is open as well as the base, and each side of the reflector is formed with an exterior reflecting surface F, so that some of the rays of light refracted by the lenses of the building light E strike the exterior reflecting surfaces F of the reflector F and are reflected laterally into the room B, and some of the rays of light refracted by the lenses of the building light E pass through the open top and bottom of the reflector F to the space below the same, so that practically the entire room or space B is properly lighted by natural light during the day.

In order to provide ventilation a duct H, of glass or other transparent material, is set on the upper open end of the reflector F, and on top of the duct II is set a tube I extending through a central opening in the building light E, the upper outer end of the tube I carrying a hood J. By the arrangement described, the duct H and the tube I form a ventilating passage for carrying off foul air which passes up into the reflector F, and the lower portion of the tube I is provided with apertures I, for the escape of foul air from the casing D into the tube I and to the outer air.

In the tube I is arranged a manuallycontrolled vent controller K, in the form of a plurality of pivoted slats adapted to be turned by suitable means into an open or closed position to control the passage of the air through the ventilator.

It is understood that as the duct H is made of glass, it does not obstruct the passage of those rays of light refracted by the building light E through the open top of the reflector F, as previously mentioned.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. An illuminating device for buildings, comprising a building light having a series of lenses, and a reflector pyramidal in shape and arranged centrally below the said building light and open at the top, the reflector having an exterior reflecting surface receiving some of the refracted light of the said lenses, to deflect the light laterally, some of the refracted light of the said lenses passing through the open reflector to the space below the same.

2. An illuminating device for buildings,

comprising a casing in the roof or ceiling of a building, the top of the casing being provided with lenses and the bottom being open, and a reflector pyramidal in shape and suspended centrally from the said casing and having its sides provided with exterior reflecting surfaces, the top and bottom of the reflector being open.

3. An illuminating device for buildings, comprising a casing rising from the root or ceiling of the building and open at the bottom, the top of the casing being provided with lenses, and a reflector in the form of a hollow body suspended centrally from the said casing and having reflecting sides in clined upwardly and inwardly from the sides of the open base of the reflector to the sides of the open top of the reflector.

i. A lighting and ventilating device for lniildings, coinnrising a casing rising from the root or ceiling of the building and open at the bottom, the top of the casing being in the form of a building light having lenses, a reflector suspended centrally below the said casing and having reflecting sides inclined upwardly and inwardly from the sides of the open base of the reflector to the sides of the open top of the reflector, and a ventilating passage extended upward from the said reflector to through the said building light.

5. A. building light and ventilator for buildings, comprising a building light, a reflector below the said building light and having exterior reflecting surfaces, and a ventilating passage extending from the top of the said reflect-or through the said building light.

6. A building light and ventilator for buildings, comprising a building light, a reflect-o below the said building lightand having exterior reflecting surfaces, and a ventilating passage extending from the top of the said reflector through the said building light, the portion of the said passage immediately on top of the said reflector being transparent.

7. A building light and ventilator for buildings, comprising a building light, a reflector below the said building light and having exterior reflecting surfaces, the reflector having an open top, a glass duct rising from the said open top, and a tube extending from the top of the said glass ductthrough the said building light.

8. A building light and ventilator for buildings, comprising a building light, a reflector below the said building light and having exterior reflecting surfaces, the reflector having an open top, a glass duct rising from the said open top, and a tube extending from the top of the saic. glass duct through the said building light, the lower portion of the said tube having vent openings.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
